OP-TEE OS ARTIK-530 port

Forked from OP-TEE/optee_os. This is the trusted side of OP-TEE and this has been ported to run on various platforms. This ForgeRock repo is used for the port to Samsung ARTIK 530 platform.

1. Introduction

The optee_os git, contains the source code for the TEE in Linux using the ARMĀ® TrustZoneĀ® technology. This component meets the GlobalPlatform TEE System Architecture specification. It also provides the TEE Internal core API v1.1 as defined by the GlobalPlatform TEE Standard for the development of Trusted Applications. For a general overview of OP-TEE and to find out how to contribute, please see the Notice.md file.

The Trusted OS is accessible from the Rich OS (Linux) using the GlobalPlatform TEE Client API Specification v1.0, which also is used to trigger secure execution of applications within the TEE.


2. License

The software is distributed mostly under the BSD 2-Clause open source license, apart from some files in the optee_os/lib/libutils directory which are distributed under the BSD 3-Clause or public domain licenses.


3. Platforms supported

Several platforms are supported. In order to manage slight differences between platforms, a PLATFORM_FLAVOR flag has been introduced. The PLATFORM and PLATFORM_FLAVOR flags define the whole configuration for a chip the where the Trusted OS runs. Note that there is also a composite form which makes it possible to append PLATFORM_FLAVOR directly, by adding a dash in-between the names. The composite form is shown below for the different boards. For more specific details about build flags etc, please read the file build_system.md. Some platforms have different sub-maintainers, please refer to the file MAINTAINERS.md for contact details for various platforms.

The Maintained column shows:

  • A green image if the platform is actively maintained: either tested successfully with the latest release (N), or is a newly supported platform.
  • An orange image if the platform was last tested successfully with release N-1.
  • A red image if the last successful test report is older.

Please see build for instructions how to run OP-TEE on various devices.


5. Coding standards

In this project we are trying to adhere to the same coding convention as used in the Linux kernel (see CodingStyle). We achieve this by running checkpatch from Linux kernel. However there are a few exceptions that we had to make since the code also follows GlobalPlatform standards. The exceptions are as follows:

  • CamelCase for GlobalPlatform types are allowed.
  • And we also exclude checking third party code that we might use in this project, such as LibTomCrypt, MPA, newlib (not in this particular git, but those are also part of the complete TEE solution). The reason for excluding and not fixing third party code is because we would probably deviate too much from upstream and therefore it would be hard to rebase against those projects later on (and we don't expect that it is easy to convince other software projects to change coding style).

5.1 checkpatch

Since checkpatch is licensed under the terms of GNU GPL License Version 2, we cannot include this script directly into this project. Please use checkpatch directly from the Linux kernel git in combination with the local checkpatch script.
